"The University of Massachusetts Amherst today denounced the unruly behavior of participants in the unsanctioned "Blarney Blowout."

Ed Blaguszewski, campus spokesman, said students arrested by Amherst Police or UMass Police will have the details of their behavior reviewed by the Dean of Students under the Student Code of Conduct. Sanctions can include suspension or expulsion from the university.

UMass Police worked throughout the day with Amherst Police to manage crowds that gathered, which occurred for the most part off campus. UMass Police reported three arrests, none of them UMass students. Other arrests were made by Amherst Police.

In the days leading up to the gathering, the university reached out to students, landlords, parents, faculty and staff in a campaign to communicate the importance of students acting safely and respecting the property of others.

In addition, the university sent letters to students who had been disciplined for alcohol-related misconduct in the past year and to students who live in off-campus housing cited for noise or nuisance complaints reminding them of the possible consequences of bad behavior."
